Download or read book Tetrad Formalism for Exact Cosmological Observables written by Ermis Mitsou and published by Springer Nature. This book was released on 2020-06-25 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel mathematical formalism, based on the tetrad formulation of differential geometry, for describing cosmological observables exactly and conveniently. It covers all the standard observables, i.e. distances, weak lensing, number counts and cosmic microwave background, and also includes a detailed derivation of general-relativistic matrix kinetic theory. All the fully nonlinear equations are derived in detail and the mathematical content is self-contained, so that readers require only a basic knowledge of general relativity. Moreover, the authors discuss several subtle issues that are usually overlooked in the literature and, in particular, issues that distinguish this formalism from the more approximative standard practice.

Download or read book Theory of Time written by IntroBooks and published by IntroBooks. This book was released on 2018-02-22 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elementary particles and the number of forces of nature are interrelated. Without mastering the basics, it is difficult to comprehend any concept of the universe like Dark energy, or cosmic world, or Black holes, and so forth. The Possibilities of other dimensions and the linear time travel are still under exploration. To have a definite idea about the presence of aliens in the outer worlds, or to learn about the infinite universe more and more, the relationship between time and space is vital. Resolving the mysteries right from the scratch becomes pivotal need of the hour, to face earthly challenges to come, with agility.
Download or read book Points Lines and Surfaces at Criticality written by Edoardo Lauria and published by Springer. This book was released on 2019-07-30 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers a fascinating journey through various non-perturbative aspects of Conformal Theories, in particular focusing on the Conformal Bootstrap Programme and its extensions to theories with various degrees of symmetry. Because of the preeminent role of Conformal Theories in Nature, as well as the great generality of the results here obtained, this analysis directly applies to many different areas of research. The content of this thesis is certainly relevant for the physics community as a whole and this relevance is well motivated and discussed along the various chapters of this work. The work is self-contained and starts with an original introduction to conformal theories, defects in such theories and how they lead to constraints on data and an extension of the bootstrap programme. This situation is often realized by critical systems with impurities, topological insulators, or – in the high-energy context – by Wilson and 't Hooft operators. The thesis continues with original research results of the author, including supersymmetric extensions. These results may be relevant non only in the high energy physics context - where supersymmetry is required for the theory to be consistent - but also for condensed matter systems that enjoy supersymmetry emergence at long distances.
Download or read book How to Build a Human Brain written by Lynne Barker and published by Springer Nature. This book was released on 2024 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zusammenfassung: "This book facilitates a dynamic approach to learning by taking us on a journey of not only the brain's anatomy, but also how it works at a cellular level, and very importantly, how the brain develops. The reader learns about how a brain is 'built' by mother nature, and what makes it 'tick'." --Rudi Coetzer, Honorary Professor at Bangor University and Swansea University, UK and Clinical Director with Brainkind How to Build a Human Brain takes a developmental approach to understanding brain structure and function. It guides readers through the evolution of the human brain, from its cellular building blocks, up to hind brain structures and functions, and through to neocortex and associated functions. In doing so, it enables students to develop a comprehensive knowledge of the relationship between brain networks and functions, neural underpinnings of functional problems seen after neuropathology, and neuroanatomy. Written in an engaging style, each chapter follows a blueprint format with subsections on issues like 'damage and repair' and 'faulty wiring' as the brain is 'built' across the course of the book. The author includes illustrative case studies and entertaining fast fact boxes to highlight the real-word relevance of each brain structure being examined. This textbook offers an accessible reference for students of neuroscience, cognitive neuroscience, neuropsychology, and biological psychology. Lynne Barker is Associate Professor in Cognitive Neuroscience at Sheffield Hallam University, UK where she also serves as Neurocognitive Theme Lead for the Centre for Behavioural Science and Applied Psychology and is a co-locator at The Advanced Wellbeing Research Centre. Her research focuses on technological innovation and new diagnostic techniques, biomarkers and interventions in concussion, stroke, traumatic brain injury and movement disorder conditions. She is currently leading a team investigating the microbiome in relation to neuropathological conditions and her team was a shortlisted winner of the 2023 Longitude Prize on Dementia.
Download or read book Visual and Non Visual Effects of Light written by Agnieszka Wolska and published by CRC Press. This book was released on 2020-07-29 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of artificial lighting extends the time of wakefulness after dark and enables work at night, thus disturbing the human circadian rhythm. The understanding of the physiological mechanisms of visual and non-visual systems may be important for the development and use of proper light infrastructure and light interventions for different workplace settings, especially for shift work conditions. Visual and Non-Visual Effects of Light: Working Environment and Well-Being presents the impact of lighting in the working environment on human health, well-being and visual performance. The physiological explanation of the visual and non-visual effects of light on humans which discusses the biological bases of image and non-image forming vision at the cellular level may be of particular interest to any professional in the field of medicine, physiology, and biology. It is one of the intentions of this book to put forward some recommendations and examples of lighting design which take into account both the visual and non-visual effects of light on humans. These may be of particular interest to any professional in the field of lighting, occupational safety and health, and interior design. "What effects on health can a light ‘overdose’ or light deficiency have? What is bad light? The authors of the monograph provide answers to these questions. Just as for a physicist, the dual nature of light comprises an electromagnetic wave and a photon, the duality of light for a physician comprises visual and non-visual effects." --------------------------------------------------------Prof Jacek Przybylski, Medical University of Warsaw "This is a unique publication in the field of lighting technology. The authors have skillfully combined both the technical and biomedical aspects involved, which is unprecedented in the literature available. As a result, an important study has been created for many professional groups, with a significant impact on the assessment of risks associated with LED sources." --------------------------------------------Prof Andrzej Zając, Military University of Technology, Warsaw
Download or read book Space and Time in African Cinema and Cine scapes written by Kenneth W. Harrow and published by Routledge. This book was released on 2022-06-28 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind to bring basic notions of contemporary physics to bear on African cine-scapes. In this book, renowned African cinema scholar Kenneth W. Harrow presents unique new ways to think about space and time in film, with a specific focus on African and African diasporic cinema. Through a series of case studies, he explores how cinema creates and represents time and space and, more specifically, how a cinema centered in African landscapes and figures accomplishes this. He reflects on the issues and problems posed by scientists when faced with the basic questions of what space and time are and their solutions or conclusions, giving both film studies and African studies scholars access to new ways to formulate their thinking about African cine-scapes. Working beyond the limits of a framework based in a postcolonial and cultural understanding of time and space, Harrow demonstrates how a scientific understanding of time and space can open up new approaches to African cinema and cinema in general. A unique, interdisciplinary book that encourages brand new ways to approach cinematic texts and, specifically, African cine-scapes.

Download or read book Experimental Film and Photochemical Practices written by Kim Knowles and published by Springer Nature. This book was released on 2020-09-29 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the contemporary status of photochemical film practice against a backdrop of technological transition and obsolescence. It argues for the continued relevance of material engagement for opening up alternative ways of seeing and sensing the world. Questioning narratives of replacement and notions of fetishism and nostalgia, the book sketches out the contours of a photochemical renaissance driven by collective passion, creative resistance and artistic reinvention. Celluloid processes continue to play a key role in the evolution of experimental film aesthetics and this book takes a personal journey into the work of several key contemporary film artists. It provides fresh insight into the communities and infrastructures that sustain this vibrant field and mobilises a wide range of theoretical perspectives drawn from media archaeology, new materialism, ecocriticism and social ecology.
Download or read book String Field Theory written by Harold Erbin and published by Springer Nature. This book was released on 2021-03-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an introduction to string field theory (SFT). String theory is usually formulated in the worldsheet formalism, which describes a single string (first-quantization). While this approach is intuitive and could be pushed far due to the exceptional properties of two-dimensional theories, it becomes cumbersome for some questions or even fails at a more fundamental level. These motivations have led to the development of SFT, a description of string theory using the field theory formalism (second-quantization). As a field theory, SFT provides a rigorous and constructive formulation of string theory. The main focus of the book is the construction of the closed bosonic SFT. The accent is put on providing the reader with the foundations, conceptual understanding and intuition of what SFT is. After reading this book, the reader is able to study the applications from the literature. The book is organized in two parts. The first part reviews the notions of the worldsheet theory that are necessary to build SFT (worldsheet path integral, CFT and BRST quantization). The second part starts by introducing general concepts of SFT from the BRST quantization. Then, it introduces off-shell string amplitudes before providing a Feynman diagrams interpretation from which the building blocks of SFT are extracted. After constructing the closed SFT, the author outlines the proofs of several important properties such as background independence, unitarity and crossing symmetry. Finally, the generalization to the superstring is also discussed.
Download or read book Fundamental Causation written by Christopher Gregory Weaver and published by Routledge. This book was released on 2018-08-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Causation addresses issues in the metaphysics of deterministic singular causation, the metaphysics of events, property instances, facts, preventions, and omissions, as well as the debate between causal reductionists and causal anti-reductionists. The book also pays special attention to causation and causal structure in physics. Weaver argues that causation is a multigrade obtaining relation that is transitive, irreflexive, and asymmetric. When causation is singular, deterministic and such that it relates purely contingent events, the relation is also universal, intrinsic, and well-founded. He shows that proper causal relata are events understood as states of substances at ontological indices. He then proves that causation cannot be reduced to some non-causal base, and that the best account of that relation should be unashamedly primitivist about the dependence relation that underwrites its very nature. The book demonstrates a distinctive realist and anti-reductionist account of causation by detailing precisely how the account outperforms reductionist and competing anti-reductionist accounts in that it handles all of the difficult cases while overcoming all of the general objections to anti-reductionism upon which other anti-reductionist accounts falter. This book offers an original and interesting view of causation and will appeal to scholars and advanced students in the areas of metaphysics, philosophy of science, and philosophy of physics.
Download or read book Probing Nucleons And Nuclei In High Energy Collisions Proceedings Of The Int Program Int 18 3 written by Alexei Prokudin and published by World Scientific. This book was released on 2020-05-29 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains proceedings of the 7-week INT program dedicated to the physics of the Electron-Ion Collider (EIC), the world's first polarized electron-nucleon (ep) and electron-nucleus (eA) collider to be constructed in the United States. The 2015 NSAC Long Range Plan recommended EIC as the 'highest priority for new facility construction following the completion of FRIB'. The primary goal of the EIC is to establish precise multi-dimensional imaging of quarks and gluons inside nucleons and nuclei. This includes (i) understanding the spatial and momentum space structure of the nucleon through the studies of TMDs (transverse-momentum-dependent parton distributions), GPD (generalized parton distributions) and the Wigner distribution; (ii) determining the partonic origin of the nucleon spin; (iii) exploring the new quantum chromodynamics (QCD) frontier of ultra-strong gluon fields, with the potential to seal the discovery of a new form of dense gluon matter predicted to exist in all nuclei and nucleons at small Bjorken x — the parton saturation.The program brought together both theorists and experimentalists from Jefferson Lab (JLab), Brookhaven National Laboratory (BNL) along with the national and international nuclear physics communities to assess and advance the EIC physics.

Download or read book LQG for the Bewildered written by Deepak Vaid and published by Springer. This book was released on 2016-10-07 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This primer offers a concise introduction to Loop Quantum Gravity (LQG) - a theoretical framework for uniting Quantum Mechanics (QM) with General Relativity (GR). The emphasis is on the physical aspects of the framework and its historical development in terms of self-dual variables, still most suited for a first, pedagogical encounter with LQG. The text starts by reviewing GR and the very basics of Quantum Field Theory (QFT), and then explains in a concise and clear manner the steps leading from the Einstein-Hilbert action for gravity to the construction of the quantum states of geometry, known as spin-networks, and which provide the basis for the kinematical Hilbert space of quantum general relativity. Along the way the various associated concepts of tetrads, spin-connection and holonomies are introduced. Having thus provided a minimal introduction to the LQG framework, some applications to the problems of black hole entropy and of quantum cosmology are briefly surveyed. Last but not least, a list of the most common criticisms of LQG is presented, which are then tackled one by one in order to convince the reader of the physical viability of the theory. A set of appendices provides accessible introductions to several key notions such as the Peter-Weyl theorem, duality of differential forms and Regge calculus, among others. The presentation is aimed at graduate students and researchers who have some familiarity with the tools of QM and GR, but are intimidated by the technicalities required to browse through the existing LQG literature. This primer aims at making the formalism appear a little less bewildering to the uninitiated and helps lower the barrier for entry into the field.
